Bought this bike a month ago, and it’s brilliant, for the money, you can’t get better, I searched long and hard for a good bike at this price point, and the btwin was a lot better than any other bikes at this price, if you get over the fact that it’s a btwin, and not a high end brand name, then it’s a real winner, the wheels aren’t the best though, I’ll be upgrading them soon, other than that, it’s superb, really really nice to ride

Ed says:

I was tempted by this bike but they ruined it with the pink details. What were they thinking? It’s not just the bar tape, either.

Daniel Hruška says:

However… just kidding, great overview! This will be my next bike in 2017, this is for sure. I’d rather ride Ultegra + Mavic Cosmic Elite on AF than 105 + Mavic Aksium on CF.

Arthur Araújo says:

I bought the bike just below this one on B’twin’s range: the Ultra 700. It has exactly the same frame and fork (just a different color scheme, which for me, actually loks much better) and comes with 105 (with a shimano RC-500 crankset) instead of the complete Ultegra, B’twin wheels instead of Mavic cosmik, and B’twin saddle instead of the Fizik Arione. Still a pretty awesome bike, nothing to complain about it. The only thing I’m changing is the saddle. Besides, the crank is 50-34 and the cassete is 11-28, so I bet the reviewer would really like too 🙂

Razvan Andrei says:

Nice review !

Jim says:

This is my next bike, just need to sell a couple of my others first.

Alex Lintern says:

Great direct-mount brakes (1:15) shows a picture of the front brake caliper with QR lever in (I believe) the ‘open’ (released) position. Is this a tech error or am I missing something? In all my years of riding the QR lever is always down (closed) enabling use of QR in case of puncture/wheel removal. I have never had a mechanical issue when using brakes like this. Do not understand why the brake is set like that.

barry herron says:

If I was to get one I would be changing the rear cassette to 11-28 or 12-30, as for the crank set its actually a compact crank set (50-34) according to the decathlon web site which is a bonus. Overall I am impressed by this bike and reviews.

Gliga Chaz says:

excellent review. Thanks

Yo-yo says:

Just put a 11-32 on there. It even looks like B’twin put a long/medium cage rear derailleur on there.

Gerald Davis says:

The price is sick!

Hello, can this bike fit 28c tires?

He is a terrible presenter, id love to see cycling weekly become as big as GCN but the presenting is a big problem. Just some feedback, no offence intended

Where can I buy this?

Ive still got those wheels on my £4,600 Cervelo and like them. Strong and i think they’re pretty light for aluminium hoops. Also got the same gear ratios as this bike and its good enough to tackle 30% gradients. Perfect gears for fast rides.
That kit at that price is amazing

Ethan Sloss says:

Fuck mate. Get the bloke in the shop to change the cassette if it worries you that much.

Cycgnr says:

Damn good review.

Ibram Guirguis says:

I’ve a question,
why is this frame approved from the uci and the mach 720 no ?

does somebody know !

kierenkd says:

I like your review – thanks. I’d love to see you review the new B’twin £800 carbon triban and maybe compare to the Btwin ultra 900 aluminium for the same price

Ed says:

Could you do a review of the Triban 540, especially as it’s now only £500.
